If I could offer critique here I would, but it's so good I can't! I have used the Photomatix software you mentioned, but found it a bit too OTT. That said, you've used it superbly here as I think subtle is the key word when it comes to using HDR. I love the composition and lighting here, but if I had to offer critique, I would maybe suggest upping the saturation a fraction, if anything. That said, I do tend to go a bit OTT with saturation myself, so maybe it doesn't need it!
